Abstract

The main cause of decline in banana production is fusarium wilt caused by the fungus Fusarium oxysporum f.sp.cubense (Foc). This disease is systemic, it is very dangerous because it can kill plants. Fusarium wilt disease ranks first in the list of diseases of bananas in Indonesia, fusarium wilt very difficult to control because it has not found a commercial banana cultivars resistant. Integrated Pest Management (Biological Control) using biological agents, one of which is the rhizosphere that has the ability to suppress the growth of Fusarium wilt (Fusarium oxysporumf.sp.cubense) in vitro. The purpose of this study was to determine the ability of an antagonist of the rhizosphere fungus to fungus fusarium. This research method is a rhizosphere fungal activity test against fusarium fungus. The results showed that 12 isolates the rhizosphere has the potential to inhibit the growth of fungi fusarium the percentage inhibition ie 82% of isolates A1, B2 D3 by 83% and 80%, A2 isolates the isolates that produce inhibition of the smallest amounting to 15%. Based on identification consists of rhizosphere fungi genus Trichoderma sp., Aspergillus sp., And Penicillium sp.

Abstract

The waste of tea powder is abundant and has not been widely used optimally. The alternative use is to use the waste as an additional medium or substitution for the white oyster mushroom growing media. The purpose of the study was to determine the effect of mycelium growth and the production of the fruit of the white oyster mushroom on combination media / tea powder substitution with sawdust. The research design used was a completely randomized design (CRD) with 4 replications. Combined treatments were M0 = 100% sawdust; M1 = 100% Tea waste powder; M2 = 75% tea powder + 25% sawdust; M3 = 50% tea powder + 50% sawdust and M4 = 25% tea powder + 75% sawdust. All treatments used the composition of the manufacture of mushroom growing media consisting of each combination of treatments, bran 10% by weight of the material and lime 0.5% by weight of the material. The parameters observed were the growth of white oyster mushroom mycelium, the rate of mycelium growth, the time the mycelium closed the substrate, the time of appearance of the fruiting body, the weight of the fruit body and the diameter of the fruit hood. The results showed that all parameters differed significantly. The best treatment is in treatment M4, followed by treatment of M3, M0 and M2.
